Patented Feb. 21 1933 UNITED STATES PATENT OFFICE NORMAN P. HARSHBERGER,OF CHICAGO, ILLINOIS, ASSIGNOR TO BAIELITE BUILDING PRODUCTS COMPANY,INC., OF NEW YORK, N. Y., A CORPORATION OF DELAWARE STRIP OF ROOFINGMATERIAL Application filed may 12,

so as to provide a pleasing appearance for the roof. One object of theinvention is to Y provide suitable means for locking down the exposedportions of the shingles and for looking the adjacent shingles together.Another ob ect is to provide for variegated figures on the roof when theshingles are laid and to accomplish this without inconvenience whenlaying the shingles.

Of the accompanying drawings, Fig. 1 is a plan view of shingles whichembody the features of my invention, showing how the shingles may be cutfrom sheets of shingle material; Fig. 2 is a plan view of one of thestrip shingles; Fig. 3 is a plan view of a number of the shingles asthey appear when assembled on the roof; Figs. 4,5 and 6 arecorresponding views of a modified form of shingle; Figs. 7 and 8 areplan views of further modified shingles; and Fig. 9 is a plan viewshowing how a further modification may be cut from strips of shinglematerial.

In making these shingles, the method pursued is to take sheets ofsuitable shingle material, such as ordinary felt and produce on onesurface bands of various colors running across the sheets, preferablyrunning longitudinally of the sheets. These bands may be formed by theuse of granulated minerals of different colors, or by applying coats ofcoloring matter to the sheets after the mineral substance, such asslate, has been applied. The strip is then cut up in a suitable mannerinto individual strips or shingles so formed that, in applying theshingles to the roof, the adjacent shingles in the same row will bereversed with reference to the way they were when out from the sheet ofsingle material.

In this instance, I prefer to cut a strip into individual shingles 10,each shingle having a slit or slot or recess 11 in one side and at anadjacent corner a lug 12. When theshingles are assembled, the lug 12 ispassed through the slot 11 of the adjacent shingle and the lug passesdown under the shingle so 1928. Serial No. 277,157.

that the two shingles are locked together. By having the lug inclinedupwardly, as indicated, the lug cannot readily be pulled out of the slot11. By keeping the lower edges of the shingles in line, the shingleswill be properly positioned with reference to each other and a unitedrow of shingles will be formed, which may be lapped upon the adjacentlower row as much as may be desired; prefierably, this lapping is thewidth of one When the rows of shingles are so formed, if the marking ofthe shingle is proper, the bands will be broken up so that, in noinstance, will similar bands on different shingles register with eachother, thus each row of bands along the roof is discontinuous so far asthe color or light effects are concerned.

The method which I pursue to accomplish this is to provide an evennumber of bands on the shingles. When the shingles are assembled, asstated, they are reversed with reference to their original position inthe sheet and, as a consequence, if there was an odd number of bands,the central band of one shingle would register with the central band ofthe adjacent shingles and, hence, there would be no break in theappearance of this band on the roof. But,-with an even number of bands,this does not occur. The number of bands otherwise is not very material,provided only that each band is unlike each of the other bands.

Hence, my method, in general, consists in providing an even number ofbands on the portion of the sheet which is to form the shingles, and incutting the shingles so that each .may be reversed with reference to theadjacent shingles when assembled. In this way, no further attention needbe given to the positioning. of the various shingles or the bandsthereon when the shingles are cut or packed for transportation or whenthey are being laid .on the roof. When being assem bled, the operatorneed pay noattention to the bands on the shingles as they automaticallywill be positioned so as not to register with similar bands of theadjacent shingles.

However, if desired, an odd number of bands may be provided and, in thisway, a

continuous band will be formed across the roof in the central portion ofeach row of shingles and, between these continuous bands, will be one ormore of the discontinuous or broken bands. This method of forming theshingles is indicated in Fig. 9. When reversed and assembled, the roofwill have alternating continuous and discontinuous bands.

I Eprefer to form the shingles as indicated by ig. 2 so that the longerdiagonal is at an acute angle with the lower and upper edges of theshingle, with one edge 13 substantially straight, and with the otheredge having serrations or steps therein. These steps I prefer to haveright-angled and of the width of the bands so as to provide therectangular shaped figures illustrated in Fig. 3. When the shingles areassembled, as indicated, the entire roof will be covered withfiguressimilar in shape but varying in light appearance. The edge 13, as it isentirely covered by the adjacent shingle. may be as indicated or may bestraight and continuous entirely across the shingle, if desired.

The length of the figures is determined by the width of the shinglestrips and the amount of lap, and the lap is determined b r the positionof the slot 11 in the edge. An the width of the figures is determined bythe width of the bands. So that the dimensions of the fi res may beeasily controlled. Also, the width of the different bands may vary ifdesired.

Figs. 4 to 6 illustrate a modified form of shingle in which the sides 15of the steps are made curved and the angles 16 and 17 are obtuse. As aconsequence of this arrangement, :1 wave line is produced at the end ofeach of the rectangular color sections, thus producing a novel andpleasing appearance on the roof which is materially unlike that of theshingles of Figs. 1 to 3. The method of producing the shingles 14 issubstantially the game as the method of producing the shingles Figs. 7and 8 show further modified shingles which may be produced insubstantially the same manner and which provide figures on the roofwhich are very similar to the figures provided by the other types.

Fig. 9 shows a further modification and a method of cutting the shinglesfrom the strips without waste. This also illustrates the shingle stripwith an odd number of bands which would produce, when laid on a roof, acontinuous band of one light effect alternatin with broken bands ofvarious other light e ects. This general effect may be produced by(providing shingles with five or seven bands an in such cases, therewill be two or three discontinuous bands alternating with one continuousband efiect.

Other modifications might be made in the details of the shingleswithout. departing from the spirit of my invention as disclosed by thefollowing claims. A particular feature of my invention, however, is theprovision of shingles which produce the figures without causing the endsthereof to register with the figures in the adjacent bands, so that eachfigure is distinctly emphasized by being in dependent of each of theother figures.

In order to more definitely define the bands and particularly thefigures, when the shingles are assembled, definite stripes may be formedon the shingles after cutting or on the shingle material sheets beforecutting between the bands, such as the stripes 20 of Fig. 7. Referringto Fig. 3 it will be seen that the rectangular figures are more clearlydefined by the edges 21 of the shingles than by the lines of demarcation22 between the bands. But, by applying stripes 20 between the bands, thefigures are clearly defined on all sides.

Particular attention is called to the fact that in each of thesemodifications the lines of demarcation lie in an extension of one ot theshingle edges. Thus, Fig. 2, the lines 25 are continuations of therespective edges 26; so that the figures have certain straight sides.each formed by a line and edge, one lying in the extension of the other.

I claim asmy invention:

1. A method of making shingles consisting in formin on a sheet ofshingle material bands of unlil re color-efiects, in formlng on one pairof opposite edges of the sheet lugs and slots, and in cutting acrosssaid sheets so as to form strip shingles, each'having a lug on one endadapted to interlock with a slot on the other end of an adjacent shingleof the parent sheet when assembled on the roof to cause registration ofunlike bands with one another.

2. -A method of making shingles consisting in forming on a strip ofshingle material longitudinal bands of unlike light effects, in formingon the side edges of the strip lugs and slits which are adapted to coactrespectively with similar slits and lugs and in cutting the strip acrossso as to form individual. shingle strips, each with :1 lug and a slit onone end, and in making the alternate cuts across the strip along zigzaglines.

3. A method of making shingles consisting in forming on a strip ofshingle material lonitudinal bands of unlike light effects, in fiormingon the side edges of the strip lugs and slits which are adapted to coactrespectively with similar slits and lugs, in cutting the strip across soas to form individual shingle strips, each with a lug and a slit on oneend, and in making the alternate cuts across the strip along zigzaglines, the zi ag lines comprising straight sections, the a ter' natesections being parallel with said bands and the others at right anglesthereto, the said lugs and slits being so positioned with relation toone another as to cause registration of the bands of one shingle withthe bands of an adjacent shingle when interlocked in assembly.

4. A plurality of shingles assembled on a roof in courses each shinglehaving the general shape of an oblong, oblique-angled parallelogram, buthaving steps in one of the long edges, a lug projecting outwardly intothe first step ad acent one short edge, and a slot in said short edgecoacting with a lug of the adjacent shingle in the same course, eachshingle having an even number of bands of unlike light effects on onesurface substantially parallel with one short edge, the bands of some ofthe shingles being unlike the registering bands of the adjacentshingles.

5. A method of making shingles consisting of forming on a sheet ofshingle material bands of unlike colornefl'ects, in forming on one pairof opposite edges of the sheet locking portions and in cutting acrosssaid sheet so as to form strip shingles, each having locking portions onone end adapted to interlock with looking portions on the other end ofan adjacent shingle of the parent sheet when assembled on the roof tocause registration of unlike bands with one another.

6. A method of making shingles consisting of forming on both edges of asheet of shingle material alternating lugs and slots, and in cuttingacross said sheet so as to form strip shingles each having a lug andslot in connection therewith, the lug and slot of one strip being on theopposite edge of the parent sheet from the lug and slot of an adjacentstrip so that half of the strips cut from the sheet must be reversedwhen they are laid on a roof to cause registration of unlike bands withone another.

7. A plurality of shingles assembled ona roof in rows, each shinglehaving a plurality of bands of unlike light effects which are adapted tobe exposed on one surface thereof, the bands of some of the shinglesbeing unlike the registeringbands of adjacent shingles,and

locking means in connection with each of the shingles engaging lockingmeans of an adj acent shingle said locking means being so positioned asto cause registration of unlike bands with one another.

8. A plurality of shingle-s assembled on a roof in courses, each shinglehaving one side edge formed with steps, a lug projecting outwardly fromthe first step adjacent the lower edge, and a slot in said lower edgespaced from the lug, said slot coacting with the lug of an adjacentshingle in the same course, each shingle having a plurality of bands ofunlike light effects substantially parallel with the lower edge, theband's being substantially equal in width to the steps and the bands ofsome of the shingles registering with unlike bands of adjacent shinglesto create a varied, ofl'set' brick-like effect.

9. A plurality of shingles assembled on roof in courses, each shinglehaving one side edge formed with steps, each shingle having a pluralityof bands of unlike light efi'ect formed thereon substantially parallelwith the lower edge, the bands being substantially equal in width to thesteps, and locking means on one shingle cooperable with complementarylocking means of an adjacent shingle to cause registration of certainbands of one shingle with unlike bands of an adjacent shingle to createa varied, offset brick-like arrangement.

10. The method of producing a shingle strip comprising forming on a webof shingle material longitudinal bands of unlike light effects, cuttingsaid web along transverse lines which extend in stepped formation acrossthe web, each step of said transverse lines being equal in length to thewidth of one of the longitudinal bands of the web or multiple thereof,and cutting the web on other transverse lines of other configurationpositioned between pairs of said first mentioned lines so as to producesimilarly shaped shingles with reversed complementary color patterns.

11. A plurality of shingles assembled on a roof in courses, each shinglehaving one side edge formed with steps and having a plurality of bandsof unlike light effects substantially parallel with the lower edge,.saidsteps being equal in width to a band or multiple thereof, alternateshingles having bands of complementary light effects and beingpositioned with their complementary bands in reverse position to createa varied offset brick- 12. Shingles having bands extendinglongitudinally thereon of contrasting color efi'ects, said shingleshaving transverse edges with stepped portions therein, one ofsaid stepshaving a width at least as great as a multiple of one of the othersteps, and being located adjacent the uppermost longitudinal edge, eachstep having within its transverse extremities a band or multiplethereof.

13. A pair of shingles adapted to be laid in alternate relationship on aroof, each shingle having its unexposed edge complementary to theunexposed edge of the other shingle and having stepped exposed edges,the steps being coincident with horizontal unlike bands of color, saidbands being complementarily reversed in alternate shingles whereby avaried offset brick like effect is created in an assembly of suchshingles.

In testimony whereof, I hereuntoset my hand.
